I have posted elsewhere a request for any recommendations for a back pack to carry an aging dog. His mileage is greatly reduced nowadays, however if I want to go out just that bit further or longer I have to leave him behind. Sometimes this is not possible.
There are various ones for sale on Amazon. What I don't want is a front carrier with holes for his legs and tail. A pram is out of the question too! He is a Parson JR and weighs about 7 kg.
